Answer:
The time taken for the vehicle to pull a 500 N rock 100 meters is :
<u>t = 5 sec</u>
<u />
Explanation:
Work = The magnitude of work is given by the product of force and displacement .
W = F x s
F = Force in Newton"N"
s = displacement "s"
In the question : F = 500 N and s = 100 m
W = F x s
W = 500 x 100
W = 50000 Nm
W = 50000 J
Power : It is the rate of doing work.The expression of power is given by :
W = Work = 50000 J
t = time
P = power = 10,000 Watt
Put the value in the formula:
t = 5 sec
